Which of the following is NOT a criterion of Just War Theory?

Just War Theory provides a framework for evaluating the moral justifications for engaging in warfare. It encompasses several criteria that must be met for a war to be deemed just. Among these criteria are the requirement for a competent authority to declare war, the necessity for a just cause, and the principle that war should be a last resort after all other options have been exhausted.

The notion that a war must be executed swiftly without regard for civilian life contradicts the principles of Just War Theory, particularly the emphasis on the protection of non-combatants and the moral obligation to minimize harm to civilians. This is in direct contrast to the ethical considerations that guide the conduct of war, which include proportionality and discrimination between combatants and non-combatants. Hence, the correct identification of this criterion illustrates a misunderstanding of these ethical principles inherent in Just War Theory.
